The twin engine aircraft departed San Cristóbal de Las Casas around 0920LT on a flight to Yajalón. While approaching Yajalón Airport, the airplane collided with a second Anson registered XB-YUB and also operated by Servicios Aéreos de Chiapas. Inbound from Tuxtla Gutiérrez , the second Anson was carrying nine passengers and a crew of two. Following the collision, both aircraft dove into the ground and crashed in a prairie. All 17 occupants on both aircraft were killed. The exact circumstances of the collision remains unclear.

The aircraft took off from Guadalajara Airport on a scheduled flight to Mexico City, carrying 38 passengers and a crew of 7. It did not follow the established climb-out procedure and crashed at approximately 2206 hours local time against La Latilla mountain, approximately 13 km from the radio beacon west of Guadalajara Airport, killing all persons aboard.

The crew was performing a test flight on this new Mexican prototype built by the engineer Ángel Lascurain y Osio. Shortly after takeoff, while in initial climb, both engines failed. The pilot elected to return for an emergency landing but on short final, the undercarriage struck a mound of earth. The aircraft overturned and crashed upside down in a field. Both occupants were killed, test pilot Carlos Castillo Segura (aged 35) and Ángel Lascurain y Osio aged 76.

After takeoff from runway 10, while climbing to an altitude of 300 feet, the pilot made a turn to the left heading 65° then continued climbing for about 400 to 600 feet when control was lost. The airplane stalled and crashed in a huge explosion in the Calle 54 Sur Street, about two km north of the airport. The aircraft was destroyed upon impact and all three occupants were killed, among them the Mexican Actor and Singer Pedro Infante who was acting pilot on this flight. A kid on the ground was also killed.

Five minutes after its takeoff from Yajalón, the twin engine aircraft struck the slope of a mountain and crashed near Petalcingo, Chiapas. All five occupants were killed. The airplane was performing a cargo flight to Tuxtla Gutierrez, carrying a load of 50 sacks of coffee for a total weight of 2,5 tons. It is believed that an engine failed during initial climb, probably because the aircraft was overloaded.
